Influence of folate/homocysteine conversion is considered to be important in the pathogenesis of Parkinson's disease (PD). However, association of the folate metabolic pathway gene polymorphisms with PD susceptibility remains unclear.

Parkinson's disease (PD) is the second most frequent neurodegenerative disorder. Previous publications have investigated the association of NOS1 and ABCB1 polymorphisms with PD risk. However, those st...
In this study, we aimed to investigate the association of four single nucleotide polymorphisms (SNPs) (MTHFR 677 C > T, MTHFR 1298 A > C, MTR 2756 A > G and MTRR 66 A > G), gene-gene i...
Polymorphisms in genes encoding the enzymes involved in the metabolism of homocysteine, such as methionine synthase (MTR) and methionine synthase reductase (MTRR), play an important function in the me...
In this study, we investigated the role of ADH2 Arg47His and ALDH2 Glu487Lys genetic polymorphisms in the development of Parkinson's disease in a Chinese population. Between January 2013 and May 2014,...
Genetic polymorphisms of the methylenetetrahydrofolate reductase (MTHFR) enzyme may influence DNA methylation. Alterations in DNA methylation patterns of genes involved in the regulation of the cell c...
Randomized double-blind placebo controlled study of reduced B vitamins in patients with major depression who were positive for one or both of the common MTHFR polymorphisms. Homocysteine l...
Scientific studies show that almost half of the people with Parkinson's Disease (PD) suffer of depression and / or anxiety. Also, clinicians reported that they exhibit specific personality...
OBJECTIVES: I. Determine basal and postmethionine plasma homocysteine in patients with premature vascular disease, cystathionine beta-synthase (CBS) or methylenetitrahydrofolate reductase...
The purpose of this research study is to learn about a possible association between cardiac denervation (the breaking down of nerves in the heart) and the development of fatigue in Parkins...
Patients with Parkinson's disease represent a significant proportion of VA elderly patients. Sleep disturbances and caregiver burnout association with this condition represent a significa...
A glycogen synthase kinase-3 type enzyme that functions in ENERGY METABOLISM; EMBRYONIC DEVELOPMENT; and NEUROGENESIS. It is also involved in PROTEIN BIOSYNTHESIS and regulates cell growth and proliferation as a component of the WNT SIGNALING PATHWAY and other signaling pathways. Certain polymorphisms in the GSK3B gene have been associated with PARKINSON DISEASE; ALZHEIMER DISEASE; and BIPOLAR DISORDER.
Proteins associated with sporadic or familial cases of PARKINSON DISEASE.
A condition caused by the neurotoxin MPTP which causes selective destruction of nigrostriatal dopaminergic neurons. Clinical features include irreversible parkinsonian signs including rigidity and bradykinesia (PARKINSON DISEASE, SECONDARY). MPTP toxicity is also used as an animal model for the study of PARKINSON DISEASE. (Adams et al., Principles of Neurology, 6th ed, p1072; Neurology 1986 Feb;36(2):250-8)
A group of disorders which feature impaired motor control characterized by bradykinesia, MUSCLE RIGIDITY; TREMOR; and postural instability. Parkinsonian diseases are generally divided into primary parkinsonism (see PARKINSON DISEASE), secondary parkinsonism (see PARKINSON DISEASE, SECONDARY) and inherited forms. These conditions are associated with dysfunction of dopaminergic or closely related motor integration neuronal pathways in the BASAL GANGLIA.
Parkinsonism following encephalitis, historically seen as a sequella of encephalitis lethargica (Von Economo Encephalitis). The early age of onset, the rapid progression of symptoms followed by stabilization, and the presence of a variety of other neurological disorders (e.g., sociopathic behavior; TICS; MUSCLE SPASMS; oculogyric crises; hyperphagia; and bizarre movements) distinguish this condition from primary PARKINSON DISEASE. Pathologic features include neuronal loss and gliosis concentrated in the MESENCEPHALON; SUBTHALAMUS; and HYPOTHALAMUS. (From Adams et al., Principles of Neurology, 6th ed, p754)
Of all the types of Dementia, Alzheimer's disease is the most common, affecting around 465,000 people in the UK. Neurons in the brain die, becuase 'plaques' and 'tangles' (mis-folded proteins) form in the brain. People with Al...
Within medicine, nutrition (the study of food and the effect of its components on the body) has many different roles. Appropriate nutrition can help prevent certain diseases, or treat others. In critically ill patients, artificial feeding by tubes need t...
Bioinformatics is the application of computer software and hardware to the management of biological data to create useful information. Computers are used to gather, store, analyze and integrate biological and genetic information which can then be applied...
